MdeModulePkg/UiApp: Retrieve the value of language menu 

In current UI code, we use oneof opcode without storage for language
menu. If we change the language form A->B, then go to another form and
then go back to the front page, the language menu always shows A. Now
we fix this issue by retrieving the value of oneof opcode(language menu)
when display it.
